[03:26] <pickanick>  Q: How can one check what 'apt autoremove' will remove?  man apt says on apt autoremove , "You should check that the list does not include applications you have grown to like even though they were once installed just as a dependency of another package."  but does not say how.
[03:30] <rbox> it tells you what its goint to do...
[03:33] <tsimpson> pickanick: you can add "--simulate" to the command to see what it will do without it actually doing anything
[03:55] <JollyRgrs> running 22.04 having crashes since going to kernel 5.15.0-100 (happened during apt upgrade). not sure how to remove it as any attempt I try via apt says to run dpkg --configure -a (which crashes when trying to build the images) and dpkg --purge for the kernel says it can't b/c of dependency issues (I booted to kernel 5.15.0-97 to try and remove 100)
[03:59] <JanC> pickanick: by default 'apt' tells you what it's going to add/remove and asks for confirmation
[04:00] <preach> not always
[04:00] <preach> sometimes apt install will not ask
[04:01] <JanC> when it only installs exactly what you asked for (no dependencies or other additional changes)
[04:06] <JollyRgrs> JanC: yes it does ask that... but once it starts and then crashes... it wants dpkg to do the --configure -a to fix it. that's where i'm at
[04:07] <pickanick> tsimpson: thanks I didn't know that
[04:09] <pickanick> JanC: preach:  yes apt does not always ask
[04:14] <preach> apt -f
[05:16] <pagios> hiiii
[05:19] <rusteh> oopsie!

[14:47] <kubast2> Any chance will see bfq i/o scheduler set as default in 24.04? I'm aware that 64 deep ncq nvme queues exist, but they don't always behave as well as having an i/o scheduler on top of ncq queue.

[17:53] <|Aspire|> hi, anyone can lend me a hand with a webcam issue?
[17:56] <bprompt> !ask | |Aspire|
[18:14] <GSMarquis> How do I set the login screen to have same scale 200% as my workspace?
[18:38] <|Aspire|> hi
[18:39] <|Aspire|> webcam led is green but black screen in cheese and other applications
[18:39] <|Aspire|> what can I do?
[18:40] <leftyfb> |Aspire|: did you try going into the cheese preferences and selecting the appropriate Device?
[18:40] <leftyfb> also, is this a usb webcam or one built into a laptop?
[18:41] <|Aspire|> yes, I have 2 cams, integrated and USB
[18:41] <bprompt> |Aspire|: is possible the app "cheese" is looking at the wrong camera, check settings
[18:41] <|Aspire|> the weird thing is that both cams are listed twice, which made me wonder whether they are mounted twice
[18:41] <bprompt> possibly looking at the one that's off
[18:41] <leftyfb> |Aspire|: what is the model number?
[18:41] <|Aspire|> causing a lock of sorts
[18:42] <|Aspire|> bprompt: I checked all of them and reduced the resolution, but to no avail
[18:43] <|Aspire|> leftyfb: I'm not sure regarding the model details
[18:43] <leftyfb> |Aspire|: lsusb
[18:43] <|Aspire|> the usb cam is DZ-X11
[18:44] <|Aspire|> this is the USB cam: Microdia Camera VR
[18:45] <|Aspire|> This should be the integrated one: Realtek Semiconductor Corp. RTS5129 Card Reader Controller
[18:45] <|Aspire|> those were the details I got for running LSUSB
[18:48] <|Aspire|> what else can I do?
[18:49] <|Aspire|> I spend most of lastnight googling for some answer, but to no ...
[18:49] <bprompt> hmmm the suspect would be drivers
[18:50] <ioria> |Aspire|, can you paste the lsusb output ?   lsusb | nc termbin.com 9999
[18:50] <bprompt> |Aspire|: yeah,  is simpler if we look at the output :|
[18:51] <|Aspire|> https://termbin.com/nazh
[18:52] <|Aspire|> https://termbin.com/5fo3
[18:53] <|Aspire|> I've added ls -l /dev/video*  - just so to make sure its not a permissions issue
[18:55] <ioria> |Aspire|, probably you're out of luck... but what are the  other applications you tried ?
[18:56] <|Aspire|> kamoso
[18:57] <ioria> |Aspire|, install guvcview and (just to be sure) relogin in the Xorg session (not wayland)
[18:57] <|Aspire|> I tried the webcam on another laptop which worked out of the box, no issues
[18:57] <bprompt> |Aspire|: did it work in Kamoso?
[18:58] <|Aspire|> bprompt: nope, same issue
[18:58] <bprompt> |Aspire|: from the lsusb output, seems the "Microdia VR" is the onboard webcam
[19:00] <|Aspire|> bprompt: thats odd
[19:01] <|Aspire|> ioria: guvcview gavemethis error: 4L2_CORE: (VIDIOC_DQBUF) Unable to dequeue buffer: No such devi
[19:02] <|Aspire|> ioria: what do you mean login to Xorg?
[19:03] <ioria> |Aspire|, you log out, get to the login screen, click the clog and select Ubuntu on Xorg
[19:03] <|Aspire|> bprompt: I'm confident that this is the external USB CAM because when I unplugg it and run LSUSB it no longer shows
[19:03] <|Aspire|> ioria: ok, will try it
[19:04] <bprompt> |Aspire|: hmmmm, I checked on the Chicony one, and they seem to only make "usb webcams"
[19:14] <|Aspire|> logged back in using Xorg
[19:15] <|Aspire|> ioria: same issue though
[19:15] <ioria> |Aspire|, what's you kernel ? uname -r

[19:32] <ioria> |Aspire|, did you select the right output in guvcview ?
[19:35] <|Aspire|> ioria: I tried all 4 options and none of them resulted in success
[19:36] <ioria> |Aspire|, no idea then; unplug it, plug it again and check 'dmesg | tail'
[19:39] <|Aspire|> it looks like the USB device dis/connected
[19:40] <|Aspire|> do you want to see the output?
[19:42] <|Aspire|> https://termbin.com/77m3
[19:45] <|Aspire|> what about the integrated cam, doesn't it seem odd that both are having the same issue?
[19:48] <ioria> |Aspire|, no idea sy
[19:49] <ioria> |Aspire|, i would try on older kernel
[19:49] <|Aspire|> what aboutthe error messages
[19:49] <|Aspire|> https://termbin.com/dwkd
[19:50] <|Aspire|> [libwebcam] Invalid or unsupported V4L2 control encountered: ctrl_id = 0x009A0001, name = 'Camera Controls'

[20:04] <younder> VFL2 is Video For Linux. Looks like you can't load a driver for that device.
[20:04] <|Aspire|> hi younder, thanks for your reply, what makes you say that,
[20:06] <younder> Normally you have plug and play. It checks the id and automatically loads the driver, but here the control is 'unsupported'. Which I presume means it is not in it's database.
[20:07] <younder> Had a similar problem with some Zed stereo cameras.
[20:08] <|Aspire|> https://askubuntu.com/questions/958987/how-to-install-webcam-camera-driver-on-ubuntu-17-04-no-device-found
[20:08] <|Aspire|> according to that link it says drivers are missin, cheese will report no devicefound
[20:09] <|Aspire|> but in my case I'm getting just a black screen
[20:11] <|Aspire|> younder: did you resolve your issue wth Zed stereo? and if so, how?
[20:12] <younder> No, they never worked properly :(
[20:13] <younder> You are dependent on proprietary drivers from the vendor. And when they don't work you are stuck. You could try contacting them..
[20:16] <|Aspire|> younder: I had trouble on windows, and was hoping it would work on linux, :))) looks like a dead end then
[20:22] <|Aspire|> I wonder whether its configuration though,
[20:22] <|Aspire|> I got this from https://webcamtests.com/ -During testing, there were errors due to which it is impossible to determine some parameters of your web camera. Reload the page and try again.
[20:23] <|Aspire|> Parameters, thats configuration right
[20:43] <Zed> wasn't  me
[21:28] <yannouri> |Aspire|> Can you provide us with more information, so we can help you? Like the type of camera
[21:31] <bprompt> yannouri: he kinda  left
[21:34] <yannouri> bprompt: Thanks
[22:37] <pflanze> Hi. I'm running a set of package installations on a 23.10 64-bit VPS. With many packages, the installation process hangs on "Setting up" for 1.5 minutes (or 10 seconds for some other packages).
[22:37] <pflanze> Load is almost 0, network is fine (a seprate ssh login is working just fine).
[22:38] <pflanze> I've rebooted the server, and am running "dpkg --configure -a" now to let it finish, still same problem.
[22:38] <pflanze> e.g. "Adding saned group and user..." is blocking, so was "Setting up ipp-usb", "Setting up usbmuxd", "Created symlink /etc/systemd/system/sockets.target.wants/avahi-daemon.socket → /lib/systemd/system/avahi-daemon.socket.", and many more
[22:39] <pflanze> Package installations have been ongoing for half an hour now.
[22:40] <pflanze> Hanging: "==> Installing the firefox snap"
[22:41] <pflanze> Before I rebooted, "top" did also hang. Since I rebooted, that one doesn't hang anymore.
[22:41] <pflanze> DNS resolution works fine
[22:42] <pflanze> (Now it has finished.)
[22:43] <pflanze> But I'll have to install more Ubuntu servers that way, so, still, what was causing this?
[22:45] <pflanze> dmesg has many "unity-greeter[1720] trap int3 ip:74175171ca0d sp:7ffd4ecb2080 error:0 in libglib-2.0.so.0.7800.0[7417516d8000+9a000]" messages (others with different numbers)
